The singer/songwriter admits he thought he'd be sick of his old hits by now, but he still enjoys belting them out onstage.
He explains: "What it is, is I'm actually trying to play the song like I know it effortlessly, but there is a pattern I must not miss, and there are words I must put with that pattern, so I'm normally still trying to get it right.
"And what I find myself doing is re-examining the work of this twentysomething. It's like it's not mine. It's not a dawdle. There's hardly anything where I switch to autopilot.
"Instead of being bored with a song, I'm still trying to look at it: 'What the hell is this thing?'"
